HOT-WATER-BQlLER CONNECTION.

SPECIFICATION forming part of Letters Patent No. 591,098, dated October5, 1897. Application filed November 30, 1896. Serial No. 613,896. (Nomodel.)

T0 or whom it may concern:

Be it known that I, GEORGE W. GRAVES, a citizen of the United States,residing at Rochester, in the county of Monroe, in the State of NewYork, have invented an Improved Hot-VVatenBoiler Connection, of whichthe following is a specification, reference being had to theaccompanying drawing.

water-boiler connection whereby hot water may be obtained from theboiler in less time than is now required and a saving of fuel effected.

My invention is fully described and illustrated in the followingspecification and the accompanying drawing, the novel features thereofbeing specified in the claims annexed to the said specification.

In the accompanying drawing the'figure is a side elevation of myimproved hot-waterboiler connection.

The object of my invention is to enable a person to obtain a quantity ofhot water from a boiler of any given size quickly or in a very shorttime, and for this purpose I connect the boiler at a point above itslower end with a suitable water-heater by a supplementary feed-pipe soarranged that only that portion of the water in the boiler above thesupplementary pipe is passed through the heater, the water below saidpipe remaining at a lower temperature than that of the water above it.highest temperature attainable in the ordinary way of connecting heatersand boilers is limited to the temperature produced by one passage of thewater through the heater until the entire contents of the boiler havepassed through. By my invention the user can expeditiously and with asaving of fuel heat a limited quantity of water to that height oftemperature which is only limited by the number of the passages of therequired water through the heater.

In the accompanying drawing, A represents the boiler; B, the heater; 0,the feed-pipe, provided with valve D and connecting the lower end of theboiler with the heater, and E the hot-water-return pipe, connecting theheater with the top of the boiler. H is the cold-water pipe, whichextends a suitable dis- It is a well-known factthat the tance within theboiler, as indicated by the dotted lines. i

I is the supplementary feed pipe, and, where different amounts of hotWater are desired, the additional pipes I I" may be employed.

The boiler may be of any ordinary or preferred construction, and it maybe supported My invention relates to an improved hot-' on a suitablestandard N.

P is a sediment-cock or discharge-valve. F is the hot-water pipe,connected with the top of the boiler and arranged to deliver the hotwater to any suitable cocks or fittings in any desired locality.

The heater B may be of any ordinary or preferred style and arranged tobe heated by any preferred kind of fuel;

In the construction shown it is supplied with gas through the pipe T,the water circulating through a coiled pipe exposed to the heat of theburning gas. ter-back of a gas or coal range may be employed as theheater.

The boiler A is provided in its side with an opening J, to which thesupplementary feedpipe I is connected. This feed-pipe mayrun directly tothe heater or it may be connected with the feed-pipe C. r

I I are additional supplementary feedpipes which are connected,respectively, to

the openings J J, located in the side of the boiler at different heightsabove the bottom.

Each of these pipes I I is' provided with a valve L L, of any preferredkind, by which the passage of the water through the pipe may beprevented. These supplementary feed-pipes may be all connected together,as

shown, or arranged in any other suitable manner so as to deliver thewater to the heater.

In the operation of my invention if the user desires the full amount ofhot water which the boiler can furnish he opens the cook or valve D inthe pipe 0, and the circulation takes place through the heater and thepipe If, however, he requiresa supply of a certain quantity of hot waterin the least possible time, he closes cock D and also valves L L, andthen the circulation will take place through the supplementary feed-pipeI, the water in boiler below the opening J remaining still and at alowertemperature than that above it. If a larger quantity of hot water isrequired, it is secured by opening the valve L, and a still largerquantity may be obtained by opening the valve L, the cock D remainingclosed at these times. The openings J J J may be located at any suitabledistances above the bottom of the boiler, according to the requirementsin any particular case.

I claim 1. The combination with a suitable waterheater, of a hot-waterboiler, the feed-pipe provided with a valve connecting the bottom of theboiler with the heater, the return-pipe connecting the heater with thetop of the boiler, and a supplementary feed-pipe connected to the boilerat a point above its lower end, whereby only the water in the boilerabove the supplementary feed-pipe is circulated through the heater,substantially as described.

2. The combination with a suitable waterheater, of a hot-water boilerprovided with two or more openings in its sides at different distancesabove its lower end, the feed-pipe provided with a valve connecting thebottom of the boiler with the heater, the return-pipe connecting theheater with the top of the boiler, and two or more supplementaryfeedpipes connected to the said openings in the boiler, and valves ineach of the said supplementary pipes below the upper one, substantiallyas described.

3. The combination with the water-heater B, of the boiler or tank A,provided with opening J in its side at a suitable distance below itsupper end, the feed-pipe 0 provided with valve D, the hot-water-returnpipe E, and the supplementaryfeed-pipe I connecting the heater with theopening J, substantially as described.

4C. The combination with the water-heater B, of the boiler or tank A,provided with two or more openings J J in its side at different pointsin its height, the feed-pipe C provided with valve D, thehot-water-return pipe E, and two or more supplementary feed-pipes I Iconnected respectively to the openings J J, the lowest of saidsupplementary pipes being provided with a suitable valve L,substantially as described.
